MySQL replication enables valuable data to be copied and stored in different locations – ensuring data security and optimal server performance.With MySQL’s prominence on the market as the largest open source database system, it has transformed the way that businesses operate and manage data. Facilitating the creation of databases and website development, MySQL is renowned for its streamlined code, accessibility and inclusion in the LAMP (Linux, Appache, MySQL, PHP/Perl/Python) stack.

As MySQL is often used to store records of information from databases and inventories from online stores, protecting valuable data is vital. With MySQL replication, an exact copy of a database is replicated onto another server, ensuring that any updates to the master database are immediately made to the other server. Replication ensures availability and reduces the possibility of data loss, which is an important backup procedure.

for example, you could stop the Slave thread on the Slave server and start it back up at a later time and it would automatically catch itself up to the Master. Pretty cool stuff.
